Potassium oxalate is a white crystal or powder made by
neutralizing oxalic acid with potassium carbonate. It is soluble
in water 1:3 but not in alcohol. Potassium oxalate was used as
an early developer for gelatin plates but is best known as the
developer for platinum prints. | [CAS DataBase Reference]

| Questions And Answer | Back Directory | [Preparation]
Oxalic acid is the main raw material for the preparation of potassium oxalate. It is prepared by reacting potassium carbonate with oxalic acid. The reaction equation is: K₂CO₃ + H₂C₂O₄ = K₂C₂O₄ + CO₂↑ + H₂O. |
| Hazard Information | Back Directory | [General Description]
Odorless white solid. Sinks in and mixes slowly with water. | [Reactivity Profile]
POTASSIUM OXALATE(583-52-8) gives basic aqueous solutions. Reacts as a base to neutralize acids in reactions that generate heat, but less than is generated by neutralization of the bases in reactivity group 10. Can serve as a reducing agent in reactions that generate carbon dioxide. | [Air & Water Reactions]
Water soluble. | [Hazard]
Toxic by inhalation and ingestion.
| [Health Hazard]
Inhalation of dust can cause systemic poisoning. Ingestion causes burning pain in throat, esophagus, and stomach; exposed areas of mucous membrane turn white; vomiting, severe purging, weak pulse, and cardiovascular collapse may result; if death is delayed, neuromuscular symptoms develop. Contact with eyes or skin causes irritation. | [Fire Hazard]
Behavior in Fire: Loses water at about 160° and decomposes to carbonate with no charring. The reaction is not hazardous. | [Chemical Properties]
Colorless, transparent crystals; odorless.
Soluble in water.
| [Chemical Properties]
The anhydrous salt, mol wt 166.22, is obtained when the monohydrate is dehydrated at 160 °C. The monohydrate is preferred as a reagent in analytical chemistry and in miscellaneous uses principally because of its high solubility as compared with other simple neutral oxalates. | [Flammability and Explosibility]
